1. -[8-12]= -[-4]= 4 (negative x negative= positive)
2. -3 + (-8)= -11 (negative+ negative= negative)
3. -4( 3/8) = -3/2 = -1 1/2 (-4 and 8 cancel out= -2 so become -3/2)
4. -7/0 = infinite answer (anything divided by 0 have infinite answer since 0 is nothing)
5. 2(-3) -1 = -6 -1= -7 (negative x positive= negative, negative+ negative= negative)
5. -(-2)= 2 (negative x negative= positive)
